LEDpar lamp, the full name is "Parabolic Aluminum Reflector", which means that the metal halide lamp is packaged in the reflector. This may be difficult to understand. The following describes the advantages and features of the LEDpar lamp and how the LEDpar lamp is used. Installation may be more thorough.
Advantages and features of LEDpar lamps:
1, LEDpar lamp uses excellent quality, high-efficiency LED lamp beads, not only good brightness, but also high color rendering index Ra, can reach more than 80, the light is close to natural light, and the human eye is well maintained.
2, LEDpar lamp drive power, carefully designed, strict selection of components, strict control of consumer quality, to ensure the life of the product.
3, LEDpar lamp, bulb lamp housing (heat sink) uses Taiwan's latest plug FIN technology, the radiator is cumbersome, the heat dissipation effect is good, the shape is also very beautiful, the performance is higher than the current cast aluminum and aluminum extrusion heat used by most manufacturers A lot better. The heat sink of LEDpar lamp adopts 6063 high-quality aluminum material, which has good heat dissipation performance, greatly reduces the light decay of the lamp bead, and ensures the service life of the LED.
How to install the LEDpar lamp:
1, LEDpar lights can be installed in any position, please ensure that the lamps are fixed and make adequate safety precautions.
2. Be sure to ensure that the voltage and frequency are adapted to the power supply and connected to the correct light, then turn on the LEDpar light.
Make sure the power is off. If you want to turn on or keep the light.Keep dry, it will keep the brightness output. If you often clean the lamp cover, it can be extended. Please use professional glass cleaning solution to clean with alcohol or chemical liquid. It, and please use a clean vacuum cleaner at least once a year.
Warning, please be careful when you install it
Please do not install the LEDpar lamp near water or other liquids.
Please do not install the LEDpar lamp in a high temperature environment.
The LED par light should be at least 0.5 m away from other objects.
Please do not look directly at the beam, otherwise your eyes will be hurt.
Open and repair the power to confirm that the power has been cut off.
Must be professional and technical personnel when repairing.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The maximum synchronous transmission rate of the original SCSI standard was 5MB / S (scsi-1, also known as narrowscsi, in 1986, the maximum support for seven devices, the clock frequency was 5MHz), and the later SCSI II specified two options for increasing the speed. One is to increase the frequency of data transmission, namely fast SCSI (in 1994, the maximum support for 7 devices) is 10 Mb / S (10 MHz) because the frequency is doubled; the other is to double the transmission frequency and increase the width of the data path from 8 bits to 16 bits. The maximum synchronous transmission speed of widescsi is 20MB / S (the clock frequency is 10MHz, in 1996, the maximum support for 15 devices).
The third generation of SCSI appeared around 1995, but there was no unified standard
1. Ultra SCSI with maximum synchronous transmission speed of 20MB / S (also known as FAST-20 SCSI, clock frequency of 20MHz);
2. Ultra wide SCSI with maximum synchronous transmission speed of 40MB / S (same as 1);
3. Ultra2 SCSI with maximum synchronous transmission speed of 40MB / S (also known as fast-40 SCSI, clock frequency of 40MHz, 1997).
Later, some newer SCSI standards appeared
1. Ultra2 widescsi with maxmum synchronous transmission speed of 80mb / S (clock frequency of 40MHz);
2. Ultra 3 SCSI with maximum synchronous transmission speed of 160MB / S (also known as ultra-160 or fast-80 wide SCSI, clock frequency of 40MHz plus double data rate, 1999);
3. Ultra 320 SCSI with maximum synchronous transmission speed of 320mb / S (also known as ultra 4 SCSI, clock frequency of 80MHz plus double data rate, 2002); 4. Ultra 640 SCSI with maximum synchronous transmission speed of 640MB / S (clock frequency of 160MHz plus double data rate, 2003, is the latest SCSI standard)
This interface is a convenient interface standard for system integration, cost reduction and efficiency improvement. More and more devices will use the SCSI interface standard. Therefore, there are many hard disks and SCSI CD-ROM drives with SCSI interface. However, due to the cost problem, they are mainly used on medium and high-end servers and workstations.
